• Device Name: OWL RADIOFREQUENCY SYSTEM, MODEL URF-2AP
• Applicant: Diros Technology, Inc.
• Product Code: GXD · Neurology
• Decision Date: Jul 1, 2002
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 882.4400
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The OWL Radiofrequency System, Model URF-2AP, intended use is for: 1. lesioning nerve tissue for functional neurosurgical procedures such as thalamotomies, pallidotomies, tractomies, and myelotomies; or 2. radiofrequency heat lesion procedures for the relief of pain.

Device Story

OWL Radiofrequency System, Model URF-2AP, is a radiofrequency lesion generator used in clinical settings by neurosurgeons. Device delivers controlled radiofrequency energy to nerve tissue via compatible electrodes. System creates thermal lesions to modulate nerve function for functional neurosurgery or to ablate tissue for pain management. Output allows clinicians to perform precise, localized tissue destruction. System operation involves monitoring and controlling energy delivery to achieve desired therapeutic effect, aiding in surgical decision-making and patient symptom relief.

Clinical Evidence

No clinical data provided; substantial equivalence determination based on device description and intended use.

Technological Characteristics

Radiofrequency lesion generator system. Includes lesion generator, radiofrequency lesion probe, and depth electrode. Operates as a Class II medical device under 21 CFR 882.4400, 882.4725, and 882.1330.

Indications for Use

Indicated for patients undergoing functional neurosurgical procedures (thalamotomies, pallidotomies, tractomies, myelotomies) or radiofrequency heat lesion procedures for pain relief.

Regulatory Classification

Identification

A radiofrequency lesion generator is a device used to produce lesions in the nervous system or other tissue by the direct application of radiofrequency currents to selected sites.

Dear Dr. Organ:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Aci) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices. good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA). it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
